0.1 ETH good for a newbie ?

Hi everyone, i'm the Colombian guy again; my question is easy i'm been in the world of cryptocurrencys for almost 2 years, but 100% of my portafolio is in Bitcoin (very conservative i know)

But recently after reading and searching about ETH and news about POS, i want to stack some Ethereum and let holding it on cold storage for almost 5 ~ 10 years (I'm 20y old)

But my question it's about the amount…. Will 0.1ETH in the future be like the 0.25BTC of today? (Just for comparison 0.25BTC puts you in the top 0.025% of people on Earth)

Thanks everyone, and sorry if the grammar isn't the best
